Selection of DGM from multiple options

[er...@thomsonreuters.com]

Could someone help me understand the rules for DGMs when multiple methods apply?  I can't seem to find anything in the specification that addresses this and I need to emulate (or call into) the rules for Eclipse.  I also tried walking through MetaClassImpl and MetaMethodIndex, but I got lost in the cache loading code.

DefaultGroovyMethods defines these two methods, in this order.  At runtime, if I have an ArrayList, sort(Iterable,Closure) is the method that is called.  Is this because 1) Iterable has wider applicability than Collection, 2) the Collection version is deprecated, 3) the Iterable version is defined last, or 4) something else?

    @Deprecated
    public static <T> List<T> sort(Collection<T> self, @ClosureParams(value=FromString.class, options={"T","T,T"}) Closure closure) {
        ...
    }

    public static <T> List<T> sort(  Iterable<T> self, @ClosureParams(value=FromString.class, options={"T","T,T"}) Closure closure) {
        ...
    }

Because the method is @Deprecated it won't be seen as a DGM extension
method, i.e. when used in the normal Groovy way.

If you call the method long-hand or from Java, both versions will be
available. Which reminds me, we were probably going to delete some of those
deprecated methods in Groovy 3.

Cheers, Paul.
